PhysioLec: Heart as a Pump Flashcards
TRUE OR FALSE: During isovolumetric contraction, there is a rise in atrial pressure.
True
TRUE OR FALSE: Cardiac outputs of both ventricles are equal
True
TRUE OR FALSE: Murmurs are heard due to narrowing of the orifice or regurgitation leading to a rippling effect, turbulent blood flow, and a vibration heard. This happens with valvular disease.
True
TRUE OR FALSE: Hearing an S3 is normal.
False
TRUE OR FALSE: (R) atrial systole occurs after (L) atrial systole.
False
TRUE OR FALSE: Sleep increases cardiac output
False
TRUE OR FALSE: The resting pressure in the pulmonary arteries is 10mmHg
True
TRUE OR FALSE: Pulse is weak during hemorrhage
True
TRUE OR FALSE: Myocardial contractility affects venous return
False
TRUE OR FALSE: If the aortic valve is stenosed, you would hear the murmur in systole.
True
TRUE OR FALSE: RV ejection begins before LV ejection
True
Because of pressure since RV only needs 10 mmHg as compared to LV’s 80 mmHg
TRUE OR FALSE: Aging produces a faster pulse wave
True
TRUE OR FALSE: The A wave corresponds to the blood regurgitation into the veins during atrial systole
True
TRUE OR FALSE: If the semilunar valves are stenosed, the bruit will be heard during systole
True
70% of blood fills the ventricles passively because of the high pressure in the SVC, IVC, and pulmonary veins. Aortic & pulmonic valves are closed.

F. None
D. Atrial systole
The phase where both AV valves and semilunar valves are closed and the ventricular muscle initially shortens a little.
A. Early diastole
B. Late diastole
C. Ventricular ejection
D. Atrial systole
E. Isovolumetric ventricular contraction
F. None
E. Isovolumetric ventricular contraction
The phase where both AV valves and semilunar valves are open.
A. Early diastole
B. Late diastole
C. Ventricular ejection
D. Atrial systole
E. Isovolumetric ventricular contraction
F. None
F. None
Relaxation of the ventricles, ventricular pressure is higher than atrial pressure but the AV valves are not yet open (Isovolumetric ventricular relaxation). Known as protodiastole and the ventricular pressure decreases in preparation for the opening of mitral and tricuspid valve so that blood will flow back again into the ventricles.
A. Early diastole
B. Late diastole
C. Ventricular ejection
D. Atrial systole
E. Isovolumetric ventricular contraction
F. None
A. Early diastole
